To win in badminton, players need to employ a wide variety of strokes in the right situations. These range from powerful jumping smashes to delicate tumbling net returns. Often rallies finish with a smash, but setting up the smash requires subtler strokes. For example, a netshot can force the opponent to lift the shuttlecock, which gives an opportunity to smash. If the netshot is tight and tumbling, then the opponent’s lift will not reach the back of the court, which makes the subsequent smash much harder to return.

Deception is also important. Expert players prepare for many different strokes that look identical, and use slicing to deceive their opponents about the speed or direction of the stroke. If an opponent tries to anticipate the stroke, he may move in the wrong direction and may be unable to change his body momentum in time to reach the shuttlecock.

Doubles

Both pairs will try to gain and maintain the attack, smashing downwards when possible. Whenever possible, a pair will adopt an ideal attacking formation with one player hitting down from the rearcourt, and his partner in the midcourt intercepting all smash returns except the lift. If the rearcourt attacker plays a dropshot, his partner will move into the forecourt to threaten the net reply. If a pair cannot hit downwards, they will use flat strokes in an attempt to gain the attack. If a pair is forced to lift or clear the shuttlecock, then they must defend: they will adopt a side-by-side position in the rear midcourt, to cover the full width of their court against the opponents’ smashes. In doubles, players generally smash to the middle ground between two players in order to take advantage of confusion and clashes.

At high levels of play, the backhand serve has become popular to the extent that forehand serves almost never appear in professional games. The straight low serve is used most frequently, in an attempt to prevent the opponents gaining the attack immediately. Flick serves are used to prevent the opponent from anticipating the low serve and attacking it decisively.

At high levels of play, doubles rallies are extremely fast. Men’s doubles is the most aggressive form of badminton, with a high proportion of powerful jump smashes.

The singles court is narrower than the doubles court, but the same length, with the exception that a serve in the single can reach the end of the court while a serve in the doubles could not. Since one person needs to cover the entire court, singles tactics are based on forcing the opponent to move as much as possible; this means that singles strokes are normally directed to the corners of the court. Players exploit the length of the court by combining lifts and clears with dropshots and netshots. Smashing is less prominent in singles than in doubles because players are rarely in the ideal position to execute a smash, and smashing often leaves the smasher vulnerable if the smash is returned.

In singles, players will often start the rally with a forehand high serve. Low serves are also used frequently, either forehand or backhand. Flick serves are less common, and drive serves are rare.

At high levels of play, singles demands extraordinary fitness. Singles is a game of patient positional manoeuvring, unlike the all-out aggression of doubles.

Mixed doubles

In mixed doubles, both pairs try to maintain an attacking formation with the woman at the front and the man at the back. This is because the male players are substantially stronger, and can therefore produce smashes that are more powerful. As a result, mixed doubles requires greater tactical awareness and subtler positional play. Clever opponents will try to reverse the ideal position, by forcing the woman towards the back or the man towards the front. In order to protect against this danger, mixed players must be careful and systematic in their shot selection.

At high levels of play, the formations will generally be more flexible: the top women players are capable of playing powerfully from the rearcourt, and will happily do so if required. When the opportunity arises, however, the pair will switch back to the standard mixed attacking position, with the woman in front.

Each game is played with 21 points, with players scoring a point whenever they win a rally (this differs from the old system, where players could only win a point on their serve). A match is the best of three games.

At the start of the rally, the server and receiver stand in diagonally opposite service courts The server hits the shuttlecock so that it would land in the receiver’s service court. This is similar to tennis, except that a badminton serve must be hit below waist height and with the racquet head below the server’s wrist, the shuttlecock is not allowed to bounce and in badminton, the players stand inside their service courts unlike tennis.

When the serving side loses a rally, the serve passes to their opponent(s) (unlike the old system, there is no “second serve” in doubles).

In singles, the server stands in his right service court when his score is even, and in his left service court when his score is odd.

In doubles, if the serving side wins a rally, the same player continues to serve, but he changes service courts so that he serves to each opponent in turn. If the opponents win the rally and their new score is even, the player in the right service court serves; if odd, the player in the left service court serves. The players’ service courts are determined by their positions at the start of the previous rally, not by where they were standing at the end of the rally. A consequence of this system is that, each time a side regains the service, the server will be the player who did not serve last time.

Details

When the server serves, the shuttlecock must pass over the short service line on the opponents’ court or it will count as a fault.

If the score reaches 20-all, then the game continues until one side gains a two point lead (such as 24-22), up to a maximum of 30 points (30-29 is a winning score).

At the start of a match, a coin is tossed. The winners of the coin toss may choose whether to serve or receive first, or they may choose which end of the court they wish to occupy. Their opponents make the remaining choice. In less formal settings, the coin toss is often replaced by hitting a shuttlecock into the air: whichever side the corked end points will be the side that serves first.

In subsequent games, the winners of the previous game serve first. These can also be called rubbers. If one team wins a game they play once more and if they win again they win that match, but if they lose they play one more match to find the winning team. For the first rally of any doubles game, the serving pair may decide who serves and the receiving pair may decide who receives. The players change ends at the start of the second game; if the match reaches a third game, they change ends both at the start of the game and when the leading pair’s score reaches 11 points.

The server and receiver must remain within their service courts, without touching the boundary lines, until the server strikes the shuttlecock. The other two players may stand wherever they wish, so long as they do not insight the opposing server or receiver.

Faults

Players win a rally by striking the shuttlecock over the net and onto the floor within the boundaries of their opponents’ court. Players also win a rally if their opponents commit a fault. The most common fault in badminton is when the players fail to return the shuttlecock so that it passes over the net and lands inside their opponents’ court, but there are also other ways that players may be faulted.

Several faults pertain specifically to service. A serving player shall be faulted if the shuttlecock is above his waist (defined as his lowest rib) at point of contact, or if his racket’s head is not pointing downwards at the moment of impact. This particular law was modified in 2006: previously, the server’s racket had to be pointing downwards to the extent that the racket head was below the hand holding the racket; and now, any angle below the horizontal is acceptable.

Neither the server nor the receiver may lift a foot until the server has struck the shuttlecock. The server must also initially hit the base (cork) of the shuttlecock, although he may afterwards also hit the feathers as part of the same stroke. This law was introduced to ban an extremely effective service style known as the S-serve or Sidek serve, which allowed the server to make the shuttlecock spin chaotically in flight.

Each side may only strike the shuttlecock once before it passes back over the net; but during a single stroke movement, a player can contact a shuttlecock twice (this happens in some sliced shots). A player may not, however, hit the shuttlecock once and then hit it with a new movement, nor may he carry and sling the shuttlecock on his racket.

It is a fault if the shuttlecock hits the ceiling.

Lets

If a let is called, the rally is stopped and replayed with no change to the score. Lets may occur due to some unexpected disturbance such as a shuttlecock landing on court (having been hit there by players on an adjacent court) or in small halls the shuttle may touch an overhead rail which can be classed as a let.

If the receiver is not ready when the service is delivered, a let shall be called; yet, if the receiver attempts to return the shuttlecock, he shall be judged to have been ready.

There is no let if the shuttlecock hits the tape (even on service).
